Community complaints since the last CLC meeting:
1. Beach Blvd. - Black dust (Jan. 12, 2018) – Strong wind and coal unloading at AMD and Stelco on Dec. 7 – 9, 2017 2. Beach Blvd. (2 homes) - Black dust (May 4, 2018) – No specific incident identified 3. Beach Blvd. – Dust (May 25, 2018) – No specific incident identified
1. Dock’s coal dust on Mar. 18, 2018 (L. Lukasik) – Emission of dust when the coal scraper dug into the base of a coal pile with more fines. 2. Black Battery emissions on Apr. 7, 2018 (L. Lukasik) – Resulted upon
3. Stack, Battery and quench emissions on May 13, 2018 (L. Lukasik) 4. Purplish stack emissions on May 24, 2018 – Short black emissions upon
X emission
Conclusion: Factors affecting the formation of NO2 that caused the brown emissions which gradually get darker nearing the Battery reversal are: the COG composition in terms of NH3 content, COG combustion conditions, flame temperature, O2 content, moisture, atmospheric and photochemical conditions around the stack outlet. How to address the issue: How to remove NO2 by subjecting or burning it in a fuel-rich flame, e.g., heating enhancement, stack burner activation, and, maximizing By-Product recovery
Resolution: The stack burner has been consistently on since May 16,
by natural gas since May 24, 2018. Since these were implemented, the
sunrise and before sunset had been significantly reduced.
Conclusion: Inadequate temperature in the coke oven during the coking process, resulting in “green coke”. How to address the issue: i. Battery heating has been supplemented by natural gas since May 24, 2018. ii. Permanent crew to clean the heating system and flues. Resolution: Similar cases have significantly reduced.
Quenching Emission Quenching Emission
Conclusion:
Inefficient removal of particulates during the quenching of coke.
Probable Cause: As designed, the quench tower has baffles that capture most coke particulates upon release by the rising steam as water gets in contact with hot coke. If these baffles are damaged or missing, particulate removal is ineffective, resulting in particulate emissions. Resolution: New baffles were completely installed May 2017. Review and increase the frequency of routine maintenance of the baffles, water nozzles, demister pump, dezurik valve and the water supply system.

Sampling Strategy – Benzene The goal is to identify additional fugitive sources of benzene to assess the quantity and frequency to answer the question, Is the source significant and can it be reduced?
